Background

A GoM operator backlogged various production pipelines for decommissioning. Pipeline product varied from single phase to threephase usage with lengths ranging from 1,800’ to 25,000’. All segments were permitted for abandonment in place, which required a minimum seawater flush volume equal to double the pipeline internal volume. Of importance, each segment needed to follow BSEE regulatory pipeline decommissioning standards.

CHALLENGE

Create an economic solution to properly decommission each pipeline segment per Federal regulatory standards with minimal disruption to normal production operations.

SOLUTION

Provide pipeline flushing and fluid filtering technical expertise. Use a water-based AquaGel® Plus pig system combined with a displacement of DynoWash® de-oiling solvent to carry out solids near the pipe wall.

Create a multiphase execution approach that would bundle pipeline assets together for lower costs and shorter schedules.
